Hi All,
I just received my new Teensy 4.0 and audio shield in the mail yesterday (directly from PJRC), and apparently broke the Teensy already. I had it running yesterday without any headers soldered to it, and went to bed (with it unplugged), woke up this morning and soldered some headers to it, and now... Nothing at all. When I plug it into my Mac, the computer doesn't recognize it as a port at all. Last night, it showed up as "/dev/cu.usbmodemXXXXXXX". When I try to upload anything with teensyduino, I get the error:
But, if I plug in my Teensy 3.2, it works fine (changing the board of course), so I don't think its my computer.
The red LED on the teensy 4 flashes briefly if I hold the programming button for a long time, but outside of that, it is completely unresponsive. My solder joints are clean, and I checked for shorts. I used 70% IPA to clean the flux, so I'm worried that maybe a little bit of water got somewhere it should't have, but other than that, I'm at a loss as to what happened.
Does anyone have any suggestions of anything I can do to get this bad boy up and running again?
Thanks!
